I fopund the Tao of Jeet Kune Do (Bruce Lee) to be a very informative read. He gives very specific, technical information on foot work, setting up strikes, even some grappling.
A very scattered read (just a mish-mosh of his personal notes complied together), but it's almost like getting personal lessons from the man himself. Recommended.
